lamellgaller

Lamellgaller is a term used to describe a specific type of gill structure found in certain aquatic invertebrates. These gills are characterized by a series of thin, leaf-like or plate-like projections, known as lamellae, that are arranged in parallel or overlapping layers. This arrangement significantly increases the surface area available for gas exchange between the organism and its aquatic environment.

The lamellgaller system facilitates efficient uptake of dissolved oxygen and removal of carbon dioxide. Water typically flows over the lamellae, allowing for diffusion of respiratory gases. The precise arrangement and number of lamellae can vary depending on the species and its specific habitat requirements. Organisms with lamellgaller often inhabit environments where oxygen levels are relatively low, necessitating a highly efficient respiratory system. Examples of animals that may possess lamellgaller include certain types of crustaceans and mollusks. The thinness of the lamellae is crucial for minimizing the diffusion distance of gases.
